Bathroom Vanity Size Guide: How to Choose the Right Vanity for Your Space

Choosing the correct bathroom vanity size is one of the most important decisions in any bathroom renovation. A vanity that is too large can make a bathroom feel cramped, while one that is too small can limit storage and counter space.

At modernbathrooms.ca, we offer bathroom vanities from 24 inches to 72 inches wide, including floating and freestanding styles, single and double sink options, and both standard and narrow-depth cabinets. This guide will help you measure your space properly and choose the ideal vanity size for your bathroom layout.

Standard Bathroom Vanity Dimensions (Width, Depth, Height)

Width: 24" to 72"
Depth: 18" to 22"
Height: 34" to 36"

While width gets most of the attention, depth is equally important. A vanity that is too deep can restrict walking space, especially in smaller bathrooms. Standard depth is around 21–22 inches, while narrow-depth vanities (18–19 inches) are ideal for tight spaces.

How to Measure Your Bathroom for a Vanity (Step-by-Step)

Step 1: Measure Wall-to-Wall Width

Measure the full width where the vanity will sit. This gives you your maximum possible vanity size.

Step 2: Account for Door Swing and Toilet Clearance

Ensure doors and drawers can open without hitting the toilet, shower, or door.

Step 3: Check Plumbing Location

Most vanities can accommodate standard plumbing locations, but very small vanities may need closer alignment.

Step 4: Measure Available Depth

Measure from the wall outward to ensure the vanity will not restrict movement.

Step 5: Consider Walking Space in Front

You should have at least 30–36 inches of clear space in front of the vanity.

Bathroom Vanity Size Chart by Width

24–30 Inch Vanities — Powder Rooms & Small Bathrooms

Ideal for half baths, powder rooms, and tight spaces. These vanities maximize function without crowding the room.

32–36 Inch Vanities — Standard Bathrooms

A very popular choice for full bathrooms used by one person. Offers good storage and counter space.

42–48 Inch Vanities — Shared Bathrooms

Provides extra drawer space and counter area. Still typically a single sink, but much more comfortable for daily use.

55–60 Inch Vanities — Primary Bathrooms

Perfect for larger bathrooms. 55" and 59" are excellent large single-sink options for those who prefer counter space. 60 inches and up is where double sinks become practical.

68–72 Inch Vanities — Large Primary Bathrooms

Designed for spacious bathrooms where maximum storage, counter space, and double sinks are desired.

Vanity Depth Guide (Why Depth Matters)

18–19 inches deep: Best for small bathrooms and narrow layouts
21–22 inches deep: Standard depth for most bathrooms
Deeper vanities reduce walking space
Shallow vanities can make small bathrooms feel significantly larger

Many customers find that choosing a slightly narrower depth is more important than reducing width.

Single Sink vs Double Sink: What Size Do You Need?

Under 48 inches: Best suited for single sink
55" and 59": Large single sink with generous counter space
60 inches and larger: Ideal for double sinks
Double sinks require more cleaning and plumbing but are great for couples

Many homeowners prefer a large single sink for easier maintenance and more usable counter space.

Floating vs Freestanding Vanity: Does Size Change the Choice?

Floating vanities create visual space and work very well in smaller bathrooms
Freestanding vanities often provide more drawer and cabinet storage
Floating styles are popular from 24" to 48"
Larger bathrooms often favour freestanding for maximum storage

Recommended Clearance Space Around a Vanity

30–36 inches of space in front
2–4 inches from side walls if possible
Avoid placing directly against a toilet or shower glass
Ensure drawers and doors can open fully

Common Vanity Size Mistakes to Avoid

Choosing a vanity that is too deep for the room
Forgetting to measure door swing
Trying to fit a double sink into a small width
Not planning for enough storage
Ignoring walking clearance in front
